These midges were reared at the United States Bureau of Ento- 

 mology June 14 to 25, 1883 from twigs of white oak (Q u e r c u s 

 alba) taken in Virginia. A number of parasites 

 were obtained from June 14th to July 3d, as well as 

 Cynipid flies. 



Gall. Large, hard, uneven galls, length 4-6 cm, 

 diameter 2 cm, somewhat resembling a potato. 

 The galls, according to unpublished Bureau notes by 

 Mr Pergande, were abundant on small oaks, all 

 the young twigs on some of the larger branches 

 being deformed (U. S. Bur. Ent. Notes). 



Female. Length .75 mm. Antennae dark brown; 



«& 



basal segments fuscous yellowish; 28 segments, the" 

 fifth with a length slightly greater than three- 

 fourths its diameter; terminal segment slightly pro- 

 duced, broadly oval. Palpi; the first segment short, 

 stout, subrectangular, the second with a length 

 about twice its diameter, narrowly oval, the third 

 a little longer and much more slender, the fourth 

 longer and more slender than the third; eyes large, 

 black. Mesonotum reddish brown. Scutellum fus- 

 cous yellowish, post scutellum a little darker. 

 Abdomen dark brown, the dorsum of the first seg- 

 ment thickly clothed with silvery white scales, 

 the second to fourth segments inclusive, with nar- 

 rowly lunate, silvery white submedian markings; 

 ovipositor pale yellowish. Wings hyaline, costa 

 dark brown, the third vein uniting with the anterior 

 margin at the basal half. Halteres pale yellowish. 

 Coxae, femora and base of tibiae pale yellowish, 

 the distal portion of tibiae and tarsi mostly reddish 

 or dark brown; claws rather long, stout, strongly 

 curved, the puvilli as long as the claws. Ovipositor 

 about three-fourths the length of the abdomen; at 

 the base a sublateral, oval group of halberd-shaped ' 

 spines; terminal lobes tapering, with a group of three or four stout 

 recurved, chitinous processes. Type Cecid. 1054.
